IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 35,223, dated May 13, H362.

To all whom it may concern:

Be it known that I, JAMES K. DUGDALE, of the city of Rich mond, in the county of Wayne and State of Indiana, have invented a new and useful Improved Hand-Cultivator; and 1 do hereby declare that the followingis a full clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a perspective view, Figs. 2, 3, 4, 5, and 6 beingparts hereinafter referred to.

The nature of my invention consists in the employment of two or moresliding frames with any approved cultivator-teeth, knives, rakes, and drill-teeth, &c., for working the ground attached to the front part of a handcart or wheelbarrow.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Letter A, Fig. 1, is a frame similar to a wheelbarrow-frame, with the side pieces, a (1, extending beyond the wheel or wheels, to which side pieces, in front of the wheel, is attached a stationary frame (represented by letter B) with three or more bars (reaching nearly to the ground when the handles of the cultivator are lifted to the height they will be when l in use) for the purpose of supporting the sliding frames, which are made the same shape as the stationary frame, with the bars 1, 2, 3, 4, and 5, Fig. 2, resting on corresponding bars of said stationary frame. The number ofbars may vary to suit the style of the tools used.

The form of the sliding frames with tools attached is shown by Fig. 2, and letter C, Fig. l They are held in their places by guides on the outside and middle bars, (shown by D D D D, Fig. 1.) The guides on the outside bars are made to lap over in front to hold the sliding framein position, and are also made to take off, when desired, to change the tools, and may be held in theirplacebya pinthrough a staple, or by the screw or spring shown at D D, Fig. 1, also shown on a larger scale by Fig. 5, in which D is the removable guide. P is the pin holding it to its place. The guides on the inside bars may be plain plates of iron or blocks of wood screwed on. A sufficient number should be used to keep the bars firmly in their places. The sliding frames are raised and lowered to any required point by pinion E, working in rack 0, attached to the middle bars of said frame. Rack c is also shown by Fig. 6 attached to a section of the frame. The pinion E is worked by a rod, F, extending to the rear, with a perforated plate, G, attached to the rear end and held in its place firmly by a pin attached to a spring and slipping into 7 the holes of said plate. The spring is pushed back when the pinion is turned by the handle H while adjusting the tools to the proper depth in the soil, which depth is indicated on the plate, that the operator may know how deep he is setting it to out. When it is set to the proper position the spring I-will hold the pin in its place, which will hold the frame. Fig. 3 shows the above-described adjusting apparatuson a larger scale. E is the pinion; F, the bar reaching to the rear; G, the pen forated plate; I, the spring holding the pin in its place; H, a handle to turn the apparatus by, and J the handle to the spring to hold the pin back while adjusting the sliding frame.

Fig. 2 represents a frame with a drill-tube attached, with a flute-tooth for covering seed any depth required, (shown on a larger scale by Fig. 4,) in which K is the drill-tube; L, the tooth for covering seed; M, the bar connectingthe flute-tooth with the drill-tube, and is raised or lowered by rod N, which rod is held in its place by a screw or pin at O.

This machine may also be used for a seedplanter by attaching thereto some approved feeding device.

I do not claim the device shown by Fig. 4, for there are similar devices in use; but

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The arrangement and combination of the adjusting apparatus composed of the perforated plate G, pin and spring I, and rod F with pinion E, working in rack e, substantially as described, and for the purposes set forth.

2. The combination of the device or guides D with the frames B and O,as and for the purpose set forth.
